It was a historic occasion, "the first time in the history of the Republic that a president has gotten married in office," as Lebel said.

Sarkozy, 53, and Bruni, 40, were married in the presence of about 20 close family and friends, Lebel said. He called the ceremony "a moment of family intimacy for the young newlyweds, of great simplicity and apparently a lot of affection between the spouses.

"I wished them a lot of happiness," he said.

Under French law, couples must tie the knot before a mayor to make their union official.

Sarkozy's openness about his private life has surprised many French, accustomed to presidents who keep their love lives under wraps.

At a news conference in January, Sarkozy revealed that the relationship was "serious" and hinted that wedding plans were in the works. But he refused to reveal the date for a wedding, saying only that France might learn about the nuptials once they had already taken place.

The couple went public with their relationship during a visit to Disneyland Paris, and they carried out their brief but highly publicized courtship in such places as the ruins of Petra, Jordan. The tabloids even showed the couple at an Egyptian beach resort, Bruni in a tiny black bikini, Sarkozy in trunks, gold chain and Ray-Ban sunglasses.

Sarkozy's approval ratings dropped during their courtship—in part, analysts say, because many older, more traditional voters were put off by his glitzy, jet-setting style.

During their romance, Sarkozy was nicknamed the "bling-bling president" by the media. He reportedly gave Bruni a pink heart-shaped diamond Dior engagement ring, while she gave him a Swiss-made Patek Philippe watch.

The wedding was the third for Sarkozy, who has three children. It was the first for Bruni, an Italian-born heiress who had a major modeling career and a well-publicized lovelife. Bruni, now a singer, dated rockers Mick Jagger and Eric Clapton, tycoon Donald Trump and actor Vincent Perez. She has a young son, Aurelien, from a relationship with philosophy professor Raphael Enthoven.
